Canonicalize more arm linux syscalls
This patch is to canonicalize more syscalls on arm linux in process record. In this patch, I also comment out some syscalls which isn't handled by GDB now. With this patch applied, two fails are fixed. -FAIL: gdb.reverse/fstatat-reverse.exp: continue to breakpoint: marker2 -FAIL: gdb.reverse/recvmsg-reverse.exp: continue to breakpoint: marker2 gdb: 2016-03-21 Yao Qi <yao.qi@linaro.org> * arm-linux-tdep.c (arm_canonicalize_syscall): Canonicalize more syscalls.
